Reaction time is the time between a stimulus — something you see, hear or feel — and your response. In a visual test it is the time from a colour change to your click, measured in milliseconds (ms).
Typical reaction times
| Reaction time | Rough level |
|---|---|
| Under 200 ms | Excellent |
| 200 – 250 ms | Great |
| 250 – 300 ms | Good / average |
| 300 ms and above | Slower than average, often due to tiredness or distraction |
These are broad, informal ranges. Test yours with the reaction time test or the F1 start lights test.
What affects your result?
- Display and mouse: a higher refresh-rate monitor and a responsive mouse shave off milliseconds.
- Alertness: tiredness and distraction slow you down.
- Anticipation: guessing can make a score faster — or cause a false start.
- Age and practice: reaction speed varies between people and with practice.
What is a good reaction time for gaming?
In most games, decisions and positioning matter more than the last few milliseconds. A reaction time in the 200s is perfectly competitive for most players. Faster reflexes help in fast shooters and rhythm games, but they do not replace game sense.
How to improve it
- Sleep and take breaks.
- Play on a high refresh-rate display and a wired mouse.
- Practise with short, focused sessions and measure your average, not your best.
- Train accuracy with the aim test as well as speed.
A note on accuracy
Online tests are informal. Browser, display and mouse delays add a few milliseconds, so use the number to compare yourself over time, not as a precise scientific measurement.
